BREECH' LOADlNG GUN.

Specification of Letters Patent.

Patented Feb. 7, 1911.

To all whom it mag concern:

Be it known that I, GEORGE S. LEwIs, of Fulton, in the county of Oswegoand State of New York, have invented a certain new and usefulBreech-Loading Gun, of which the following is a specification.

My invention relates to breech-loading guns, and has for its object theproduction of a cooking mechanism, which is particularly simple inconstruction, economical in manufacture, and efficient and durable inuse; and to this end, it comprises the combinations and constructionshereinafter set forth and particularly pointed out in the claims.

This invention is susceptible of various embodiments, but for thepurpose of clearly disclosing the same, I have illustrated in theaccompanying drawing, and will hereinafter describe in connectiontherewith, what is now conceived to be a preferable embodiment.

In describing this invention, reference is had to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figures 1 and 2 are'sectional views, partly in elevation, of a portionof a gun equipped with my cocking mechanism, the barrels be ing shown intheir normal position in Fig. 1, and as broken or dropped in Fig. 2.Fig. 3 is a sectional view, partly in elevation, of means illustrated inthe preceding figures, the fore-end being removed. Figs. 4 and 5 are,respectively, inverted plan and end view of the frame. Fig. 6 is an endview of the detached fore-end. Fig. 7 is a. plan of the detachedlocking-bolt, the coupling-piece, and the spring connected to thecouplingpiece, the top lever being indicated by dotted lines. Fig. 8 isan isometric view of the detached hammers, the pivotal pin therefor, andthe cooking member associated with the frame.

The frame 1, hammers 2, barrels 3, foreend 4, and ejector 5, are of anysuitable form, size and construction. The means for cocking the hammers2 consists of cooking members 6, 7, the member 6 being associated withthe frame 1, and having its front end formed with a substantiallyhook-shaped part 8, and having its rear end loosely mounted on thepivotal pin 9 and provided with lateral extensions 10 engaging thehammers 2 at the rear of said pin 9. A suitable spring 11 bears upon therear end of the cooking member 6 and engages the trip 12 for thelockingbolt 13. The cocking member 7 is associated with the barrels 3,is reciprocally movable in a direction substantially parallel to theline of movement of the extractor 14, and is provided at its forward endwith an extension 15 movable in a socket 16 in the barrel-lug 17 intoand out of engagement with a spring 18 seated in said socket. The rearend of the cocking member 7 is formed with an ex tension movable along alengthwise engag ing face 19 provided on the barrel-lug 17,

said extension being formed with a guide 20 which receives a part, as apin 21, fixed to the barrel-lug beneath the engaging face 19, andconsists of a slot open at its rear end and extending through oppositesides of the cooking member 7 A suitable projection 22 extends upwardlyfrom the intermediate portion of the cooking member 7 into a recess 23in the extractor and cooperates with the end walls of said recess. Anextension 24 depends from the intermediate portion of the cooking member7 and is formed with a substantially hook-shaped part coacting with thehook-shaped part- 8 of the cooking member 6.

When the parts of the gun are in their normal position, as indicated inFig. 1, the cooking member 7 is in its extreme forward position, thespring 18 being slightly compressed, the rear face of the projection 22being engaged with the rear end wall of the recess 23, and the extension24 being in such position that upon the detachment of the fore-end 4,Fig. 3, the barrels may be readily removed from the frame of the gun.Upon the initial dropping movement of the barrels, the ejector 5 movesthe extractor 14 rearwardly, thus separating the rear end wall of therecess 23 from the rear face of the projection 22, whereupon the spring18 forces the cooking member 7 rearwardly and operatively engages theextension 24 with the cocking member 6. As the drop-ping movement of thebarrels continues, the front wall of the recess 23 coacts with the frontface of the projection 22 and forces the cock ing member 7 rearwardly toits position assumed in Fig. 2 for maintaining operative engagement ofthe cooking members 6, 7. When the dropped barrels are returned to theirnormal position, the rear wall of the recess 23 engages the rear face ofthe projection 22 and returns the cocking member 7 to its normalposition.

The locking-bolt 18 is provided with an engaging face 25 which coactswith the rear extension of the barrels, is arranged above and at therear of the pivot for the barrels, and extends upwardly and forwardly atan angle to the axis of said barrels. This locking-bolt is usuallyarranged with its lengthwise axis at an angle to the axis of thebarrels. A coupling-piece 26 is suitably fixed to, and movable with, thetop lever 27 and is provided with an arm 28 coacting with thelocking-bolt 13. A spring 29 is connected to the coupling-piece at apointsubstantially diametrically opposite to the arm 28. Thecoupling-piece 26 is generally formed with a lengthwise substantiallyupright bearing face 30 engaged by a roller 31 which is movable with thetop lever 27, and tends to prevent displacement of the locking-bolt andto reduce the friction incidental to the move ment thereof. Thedescribed arrangement of the locking-bolt, and the means for coactingwith the same, is particularly simple in construction and eflicient inoperation.

hat I claim is 1. In a breech-loading gun, a barrel having a lug formedwith a socket, a part fixed to the barrel-lug, a hammer and means forcooking the hammer comprising a member associated with the barrel andreciprocally movable relatively thereto, said member being provided atone end with an extension arranged in the socket and at its other endwith a slot for receiving the fixed part of the barrel-lug, the slotopening through the rear end of said member. substantially as and forthe purpose described.
